BASIC APPROACHES IN MINIMALLY INVASIVE CARDIAC SURGERY (MICS) AND ITS SELECTION

Recently, minimally invasive cardiac surgery (MICS) has been developed and popularized as a less stressful and less invasive technique in the field of cardiac surgery. There are eight currently available MICS approaches for open heart surgery. The optimum approach should be selected for each patient based on the results of preoperative examination including chest X-ray, computed tomography, and angiography.
Between December 1996, when we first introduced MICS for mitral repair, and the end of November 1998, we performed MICS in 67 patients [excluding cases of MIDCAB]. These included 11 patients who received the Port-Access (Heartport, Inc.) system. Although no patients died in hospital stay, one died of cerebrovascular bleeding eight months later. All patients were evaluated in the outpatient department as being NYHA class I.
In view of future technological progress, we expect that MICS will gradually become more widespread in cardiac surgrey.
